Hayden Panettiere reduced her mother to tears when she got a tattoo without her permission. The sexy 18-year-old Heroes star only got the etching done a year ago and kept it hidden from her parent.

She says, "It's a Leo symbol on my ankle. My mom didn't see it for ages."

The tattoo didn't remain a secret for a long as an acting job intervened, revealing the hidden body art.

She continues: "Then, I was being body-scanned for a special effect on Heroes. And she saw it, tried to rub it off and suddenly I realized. Her eyes welled up."
